Here is Spike's tank with his new florescent light. I don't think I'll EVER go back to the incandescent lights. The $10 was totally worth it.
Just look at the colors this light had brought out on him! Sry for the blur he was swimming alot xD

I don't have a tank to share yet [unless you'd like to see an empty one? lol] but I was hoping I could ask a quick question?

I have an 10 gallon tank that I'm not using, and in a few weeks I intend to get a betta because they're really pretty to look at. I see a lot of people use colourful gravel in their tanks- it's pretty pretty. But I was wondering if it is safe to use sand in with a betta fish? That's what I generally have on hand because that is what I use with my turtle *-*
